Donna Oddy, a biologist with Innovative Health Applications at NASA's Kennedy Space Center in Florida, releases an endangered green sea turtle into the Mosquito Lagoon, which is part of Florida's Indian River. The turtle was one of more than 300 that were "stunned" during two cold snaps in December 2010. Turtles that were stunned multiple times will be released in the Sebastian area of the Indian River, which often offers warmer water and could help prevent future stuns as winter progresses.
